ARTHUR FRANCIS ENGEL, OF NEW YORK, N. Y.

EYELETING-MACHINE.

Application filed January 22, 1915.

To ail whom it may concern Be it known that I, ARTHUR FRANCIS ENGEL, a citizen of the United States of America, residing at 3059 Broadway, in the city, county, and State of New York, United States of America, have invented new and useful improvements in Eyeleting-lvlachines, of which the following is a specification.

This invention relates to eyeleting machines, and more especially to machines of this type adapted to be used in fastening papers together.

The primary object of the invention is to provide a machine which is adapted to be used in connection with strips of connected eyelets, such as are shown and.- claimed in my prior Patent No. 1,071,406, dated August 26, 1913, and by means of which the strip will be fed positively and eacheyelet Will be severed from the strip at the proper time and quickly inserted in position and upset or riveted at one and the same operation.

A further object is to provide a device wherein the functioning parts are constructed to move with the required speed at certain stages in each operation and to receive the necessary application of power at certain other stages as the operating handle is moved steadily and with a uniform application of pressure by the operator.

Another object is the provision of a device which will be positive in actlon and which will not be likely to get out of order.

Other objects will in part be obvious and in part pointed out hereinafter.

In the accompanying drawing, showing .an illustrative embodiment of this invention and in which the same reference characters indicate like parts in the several figures: Figure 1 is a side elevation of the device, part being broken away and shown in vertical section for the sake of clearness; Fig.

2 is a top plan view, the handle of the device being removed and the body of the same being broken away on the section line 2 2 of Fig. 1; Fig. 3 is a front elevation of a portion of the device; and, Fig. 4 is a bottom plan View, a portion of the device being broken away.

In the drawings, the numeral 5 designates the body or frame of the machine which includes a base 6. This body is constructed so as to be hollow in order that it may accommodate and house the operative parts The front of the body 5 Specification of Letters Patent.

provide upper and lower jaws 8 and 9 respectively. An anvil 10 is fitted within a socket 11 provided therefor in the lower jaw 9. The anvil is provided upon its upper end with a low projection 12 for a purpose which will be set forth more fully hereinafter.

The upper jaw 8 is provided with a cylindrical vertical opening 13 which is arranged in vertical alinement with the anvil, 10. This opening is intended to serve as a hearing opening for the lower end portion of a plunger 14: which is mounted for vertical reciprocation within the body 5, its upper end being guided by a cross-head 15 whose laterally projecting portions are slidably engaged within the vertical grooves 16 provided in the sides of the body extending through the upper end of the same. A limiting member 17 which is formed preferably from sheet metal is adapted to be mounted upon the upper jaw 8 and is provided in its uppermost supporting portion with an aperture 18 for the reception of the plunger 14:, whereby the said member is secured in its applied position. An inbent tongue 19 is provided at the lower edge of the member 17 and underlies the upper jaw for a purpose which will be set forth hereinafter. A helical compression spring 20 is mounted upon the plunger 1-1 and is interposed between the member 17 and the crosshead 15 in order that the plunger will -be supported normally by this spring in its inoperative position with itslower end projecting into the bearing opening 13 of the upper jaw to a slight extent only. The

upper end of the plunger is curved from front to rear so as to present a convex bearing surface 21 for engagement with the actuating surfaces of a cam 22 which is wardlv projecting inoperative position also.

Directly in rear of the concavity 25 the actuating surface of the cam extends away from the pivot of the handle abruptly in a radial direction as at 26. It is then formed conis indented just above the base as at 7 to vex so as to-provicle at a point-more distant from the pivot a less abruptly inclined portion 27. The actuating surface is then extended abruptly away from the pivot as at 28 in the form of a convex curve, but it then becomes less abrupt as at 29 and nearly approaches a regular curve concentric to the handle pivot; The functions of these peculiarly curved portions of the actuating surface of the cam will become apparent as the description progresses.

The plunger 14 is provided with a medial longitudinal bore, 30, whose uppe portion is large r thanits lower portion'31, whereby a limiting shoulder 32'is provided at the juncture of the two bore portions. An eyelet holding pin 33 is mounted for reciprocation within the reduced portion of the plunger bore, and is provided at its upper end with a limiting flange 34 which is adapted to engage the shoulder 32 normally t6 'ini ar th p n n i d pen n Op r t position with its lower end projecting below the lower end of the plunger to a convenient distance, as shown particularly in Fig. 1. A helical mpre sio pri g is mo nt within the upper, main portion. of the plunger bore 30, between the cross-head 15 and the upper end of the holding-pin 33, so as to maintain the latter normally .in its operative position, When the plunger 14 is in its elevated, inoperative position, the lower end of the holding pin '33 will be disposed at apoint slightlyelevated above the engagingend of the retaining tongue 19 of the nember 1T.

A transversely extending cutting blade 36 is mounted upon-the body 5 beneath the upper jaw 8 and extends through the indentation 7. This blade isarranged substantially at a tangent to the opening 13 in the upper jaw, and consequently to the imaginary cylinder. which constitutes the path or the plunger 14, inwardly. of the frame, with its active edge N/disposed. uppermost. The

bl d curet9 t frame P e bly i a removable manner by means of the attachsaws 38in order that it be replaeed readily, by a hewblade. when it becomes wornexce ssively bearing opening 39 is provided in the rear wall of the, body 5, substantially on a level with the cutting blade 36.- "An eyelet guide member 40, is mounted within the body for horizontal reciprocation from frontto rear and for slig-ht verticaloscil-latory' movement, in which latter movement it is fulcrumed by the edges of thefbo dy. opening 39 through which the rear endof the guide member is adapted to p je The. guide member 40. is constructed preferably of: sheetmetal which bent into such a form that it will fit the. eyelet strip is wil u p'o l We as u de. h sitiid na y; the? T g id was... saetaiaaiaisniaa audits areas at v against undue movementin this direction.

The lower edges of the side walls 41 are beveled rams point adjacent to the said shoulders 42" upwardly to the forward end of the guide member as at 4,3. The portions of the said edges which intervene between the said beveled or inclined portions and the shoulders 42 and which are indicated by the numeral 44, are adapted to bear against the active edge 37 of the cutting blade 36. when the guide member is in its operative position to support the forward end of the same rigidly therein. The forward end of the guide member 40 will project through the path of movement of the plunger 14 when in its operative position, but its top wall 45, is provided with a longitudinal slot opening through the front edge of the said Wall through which the holding pin 33 may project. A longitudinally extending spring tongue 47 is secured at its rear end medially to the upper Wall 45 of the guide member and is arranged with its forward end overlying the slot 46. and projecting forwardly to a point where it is spaced from the forward end of the guide member at such a dis tance that it will be disposed immediately above the cutting blade 36 when the guide member is in its operative position; This spring tongue constitutes a locking member and is provided at its forward, free end with eyelet engaging teeth 48 which project downwardly from the sides of the said lockingmember. The front edges of the teeth 48 are arranged at right angles to the plane of the upper surface of the locking member, whereas the rear edges of the sai teeth are inclined. limiting surface 49 is provided at ashort distance below the upper jaw 8 and in rear of the bearing opening 13 in spaced relation thereto for engagement with the locking member 47 in spaced relation to its free end to limit the upward movement of the guide member when moving into its operative position.

A helical retracting spring 50 has one end thereof connected with the base 6 of the machine directly in rear of the indentation 7 as at 51. This spring projects upwardly and rearwardly from its point of connection 51 with the base and has its opposite end connected with the guide member 40 adjacent to the rear end of the same as at 52. This spring is adapted normally to mainin the wcle msm et i its f rwa d y i '58 is pivotally mounted within the upper portion of the body 5 upon a transverse pivot pin 54. This lever includes a forwardly projecting arm 55, which is arranged within the path of the cam 22, and a depending arm 56. The lower end of the arm 56 is connected with the guide member 40 at a point adjacent to the point of connection 52 of the retracting spring therewith, by means of links 57, whereby the guide member will be thrust rearwardly upon depression of the handle 23 to bring the actuating surface of the cam 22 into engagement with the arm 55 of the bell crank lever.

The operation of the device will now be described.

Assuming that a strip of connected eyelets 58 is inserted into the guide member 4:0 through the open rear end of the same, and is thrust forwardly until the foremost eyelet is in the path of movement of the plunger 1% and is engaged between the engaging end of the stationary tongue 19 and the securing teeth 4:8 of the locking member :7, the handle 23 is depressed gradually. During this movement of the operating handle, the abruptly inclined portion 26 of the actuating surface of the cam 22 will move into sliding engagement with the convex upper end of the plunger 14 so as to thrust the said plunger downwardly at great speed until the holding pin 33 carried by the plunger has penetrated the foremost eyelet and the lower end of the plunger itself has engaged the said eyelet to force the same downwardly to bring the tie-piece connecting this eyelet with the next succeeding eyelet into operative engagement with the cut ting edge 37 of the blade 36. At the same time, the portion 29 of the actuating surface of the cam will have engaged the arm 55 of the bell crank lever so as to force the same downwardly and thus rock the lever to move the guide member -l0 rearwardly through the medium of the rigid links 57. The guide member will be moved longitudinally to the rear against the action of the retracting spring 50 and also will be oscillated to a slight extent upon the edges of the bearing opening 39 in the body 5 as a fulcrum whereby the forward end of the said guide member will move downwardly and to the rear, the inclined edges as of the side walls of the said member just clearing the cutting edge of the blade. During this movement of the guide member, the foremost eyelet and the entire strip consequently will be retained in forwardly disposed position owing to the engagement of the holding pin 33 with the said eyelet. At the instant the said tie-piece of the eyelet strip comes into engagement with the cutting edge of the blade, the less abruptly inclined portion 27 of the actuating surface of the cam will engage the upperend'of the plungenso as to retard the dle.

speed of the plunger but at the same time increase the power which is applied to the eyelet to force the tie-piece of the strip against the cutting edge of the blade 36 during the operation of severing the said tie-piece. When the eyelet is completely severed from the strip, the lower end of the holding pin 33 approaches the projection 12 of the anvil, with which it inatriculates, so closely that the said eyelet cannot escape from its engagement with the said pin but will fall, guided by the pin, onto the upper surface of the paper or the like (not shown) which may be mounted between the jaws of the machine overlying the anvil. Just as the cutting operation terminates, the abruptly inclined portion 28 of the actuating surface of the cam engages the upper end of the plunger so asto again accelerate the speed of the downward movement of the same until the upper end of the plunger has become engaged by the less abruptly inclined portion 29 of the said actuating surface, at which stage in the operation the lower end of the holding pin will have become engaged with the surface of the paper interposed between the same and the projection 12 of the anvil, and the plunger will have moved downwardly over the checked holding pin until the lower end of the plunger has become engaged with the eyelet to force the lower edge of the latter through the paper, whereupon it will be tripped or upset by its engagement with the anvil in the manner desired to be attained. The eyelet itself thus serves as the punch of the device. Owing to the peculiar formation of the actuating surface of the cam, the plunger will be moved slowly and with the exertion of considerable power at the stages in the operation where such power is most needed. During the other stages of the operation, however. the plunger will move rapidly and thus without loss of time. At the end of the stroke of the piston, the handle 23 is released. and the spring 20 will serve to retract the plunger and the operating han- The spring 35 will at the same time retract the holding pin 33 and the spring 50 will retract the guide member 40, thereby moving the latter into its forwardly disposed operative position. During the preceding rearward movement of the guide member d0, another eyelet was brought into operative position in advance of the teeth 48 of the locking member 47, owing to the fact that the end of the locking member bearing the teeth was deflected upwardly by engagement of the said eyelet with the inclined rear edges of the said teeth. This new eyelet therefore has been moved into operative relation to the plunger and into a position wherein it is retained efiectively between the said teeth of the locking member and the engaging endpf the retaining tongue 19 fixedly disposed upon the jaw 8. As the operating handle is manipulated in the manner set forth repeatedly, the eyelets will be fed, severed and fastened in the paper successively. The last eyelet will be operated upon just as effectively as any of the others, owing to the construction of the functioning parts of the machine.
